It takes a lot of faith to be put under gene therapy. Especially when you're using a permanent lentivirus to do the job. I understand how it feels to be plagued with a lifelong condition, and the desire to rid of the disease, and therefore the want to put yourself through a substantial risk of death or disability in order to rid of it. For my part, I've accepted who I am (easier since my quality of life is still pretty good). The desire to rid of my condition is still there of course, and I've learnt to live with it.
Thank God for the success of this treatment, it takes tremendous amount of faith (or desperation) to be able to do such a thing. The consequences, should the treatment go wrong, is really quite painful. May the person make good with his newfound freedom.
